Abstract

This study was carried out to determine the average radiological pelvic brim index of the people in South-South Nigeria and to determine if there is sexual dimorphism and racial differences when compared with other races. Anterior posterior radiographs of adult pelvis (age range, 18-75 years) were evaluated. Five hundred and eighteen (518) radiographs (259 males and 259 females) were those of the South-South people of Nigeria. The parameters considered are: anterior posterior diameter, transverse diameter and pelvic brim index. The mean values of anterior posterior diameter, transverse diameter and pelvic brim index of males in South-South Nigerian people were 115.33±13.53 (mm), 128.33±10.01 (mm) and 90.08±10.07 respectively while those of their females were 125.70±13.46 (mm), 141.44±10.51 (mm) and 89.10±9.49 respectively. The mean anterior posterior diameter and transverse diameter of females was significantly higher than that of the males (p<0.05). There was no significant difference between the pelvic brim index of males and females in South-South Nigerians (p>0.05).When comparing our values with other works done by different authors, there were a racial difference. There was also, a strong positive correlation between pelvic brim index and anterior posterior diameter (p<0.05). Knowledge gained from this work will be useful to the obstetricians, physical and forensic anthropologists, Archeologist and radiologist for sex and race classification of human pelvis.
